    How Does AI Detection Work?

    The AI checker specializes in detecting content from ChatGPT, Claude and Meta’s LLaMa. The detection models break apart written content into machine readable pieces that are then analyzed and compared to known patterns of human written text versus that of AI models. What you get is a confidence score giving you the likeliness of whether the text was written by a person or artificial intelligence. Submit that paper with confidence or check that the words you’re about to read are actually human.
